Wow, that's nasty. I'd put a front axle repack on my short list. Unless you know otherwise, that looks like they've never been opened since new.

So does the second picture look like diff oil?

The second picture looks like dirty ass. :flipoff2:

Thats pretty much how my front axle looked when I got my truck in November. Now? Clean as a whistle with a little tiny bit of the moly thru the wipers on the back. I think I over filled it in my excitement to be finishing the job....at 1:30am:bang:
 
I just bought this truck about a month ago and don't know the history at all. Truck has 125K. I would bet you are correct that the axel has never been repacked. I may also need to fix the diff vent but it seems obvious the seal is leaking on the driver side at least. I just hate to have to do this in my driveway in the winter time. I just got my factory service manual today so I will be reading up on the project. Thanks for all the replies.
 
F the manual. Just read the writeup on here. I just completed mine for the first time. Its an easy albeit messy job. Hardest part was pulling the old oil seal out, even with the seal puller.

Well, if tearing into it isnt feasible due to weather and you have to drive it, then I'd would absolutely fill the knuckle with some more moly grease. Thats a band aid, but better than nothing.
 
If you've got the time and space, do it soon. I did mine back in Oct. with a friend who knew no more than me and a guy that had done it once before. Props to Jacob that came over to help and instruct, but I think, with my limited experience, it would have taken an additional 2+ hours or so without him to get it done. I now drive knowing that my front end is properly lubed, sealed, and no pending super expensive birf repair is awaiting... dig in, get dirty, figure out what makes these wonderful rigs tick!
 
That's things long gone and the oil seals too for sure. You need to do both wheels. I'll bet the previous owner pumped grease into the diffs in a vain attempt to hold off losing everything in the flow and that's why you had that thick grease like stuff came out.

Bite the bullet and be sure a competent person gets a good look see at your Birfs before you re-assemble. If it were easier, I'd also look at the diffs, but I suppose your ears will give you the story in time.
